Every API, one clean contract.

Follow the redirect chain to the final URL (hop-by-hop, every status observable).

{
  "url": "http://github.com"
}

Resolve then strip tracking params (utm_*/fbclid/gclid…) → canonical URL.

{
  "url": "https://www.example.com/?utm_source=a&fbclid=b&id=42",
  "follow": false
}

Detect the affiliate network/params/merchant across the whole redirect chain.

{
  "url": "https://www.amazon.com/dp/B08N5WRWNW?tag=myaff-20",
  "follow": false
}

Identify marketplace + product-id + the ReefAPI engine that can fetch the product.

{
  "url": "https://www.amazon.com/dp/B08N5WRWNW",
  "follow": false
}

Link unfurl: OpenGraph + Twitter-card title/description/image/favicon (Slack/Discord style).

{
  "url": "https://www.example.com/"
}

Heuristic URL-risk flags (ip-host, non-https, punycode, userinfo, high-abuse TLD, long/multi-shortener chain, cross-domain) + risk level/score.

{
  "url": "https://www.amazon.com/dp/B08N5WRWNW"
}

One call: resolve + normalize + detect_affiliate + product_hint + preview + safety.

{
  "url": "https://www.amazon.com/dp/B08N5WRWNW?tag=aff-20&utm_source=x"
}

Resolve up to 20 URLs concurrently in one call (each independently SSRF-guarded).

{
  "urls": [
    "http://github.com",
    "https://www.example.com/?utm_source=z"
  ]
}
